High-Intensity LED Backlight Technology

Lumex today announced the launch of the QuantumBrite™ line of LED backlight technologies. Available in edge lit and chips on board formats in both white and vivid color options, the QuantumBrite line of backlight products provides more than twice the intensity of traditional backlights.  In particular, the white QuatumBrite LEDs provide high-intensity brightness of up to 10,000 nits allowing for full daylight visibility. The QuantumBrite family is available in off-the-shelf sizes, and a U.S.-based team of experts is available to create semi- and custom- solutions for high or low volume specialty applications.

The QuantumBrite family represents a new generation of backlight technologies, ideal not only for traditional applications such as flat panel displays and indicator lighting, but also for non-traditional applications, such as logo enhancement or indirect lighting.  Now homeowners can have LED panels installed in walls, reducing the need for floor lamps and introducing an innovative contemporary element into their living space.  The QuantumBrite line of backlight products can also be used for non-traditional uses such as refrigerator walls, test and measurement applications for jewelry grading or microscopes.

“Whereas many LED backlight providers often require a 50,000 or 100,000 piece minimum order for customized LED backlight solutions, customized QuantumBrite backlight solutions can be completed for orders as small as 5,000 pieces, making this an ideal product and service for high-value, small volume applications such as medical devices, security equipment and industrial controls,” says Yasoob Ahmed, Manager of Display Technology at Lumex. “In addition to high-intensity light performance, what differentiates the QuantumBrite family of LED backlight technology is the fact that our U.S.-based team of specialists is available to provide expert system advice integrating a customer’s specifications for size, power and heat-management requirements, mounting needs, brightness targets and color selection to create a solution that is custom tailored to meet specific application needs.”

The QuantumBrite edge lit LED backlights are available in both with- and without-reflector formats. The reflector format captures more light than does the without-reflector format, and can enhance light output up to 20%.

LED backlights have several advantages over alternative backlight technologies, such as CCFL backlights. Unlike CCFL technologies, LED backlights are available in any color including tunable RGB, or even custom colors like pink, purple and turquoise because of the inherent nature of LEDs. Backlights are able to withstand both shock and vibration in some of the most demanding applications, and have an average lifespan of 100,000 hours – compared to the average CCFL lifespan of only 20,000 hours.  LED backlights can also be produced in much smaller packaging than CCFLs, and are more environmentally friendly than CCFLs, which contain hazardous materials such as mercury.

The RoHS compliant QuantumBrite LED backlights range in size from 1x1 inch to10x10 inches.  Samples of these devices are available from stock, with custom production quantities in 6-8 weeks and standard production quantities in 4-6 weeks.  Pricing is dependent on quantity ordered, and is approximately $1 to $20 per unit in production quantities dependent on size, color and quantity ordered.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
